Abstract
Cellulosic ion-exchange materials, 0-10% cross-linked, are used to extract dissolved materials (especially those giving large ionic species) from liquid media by ion-exchange interaction conducted under agitated conditions produced by an agitator located in the reaction zone or by certain turbulence-inducing arrangements. The cellulosic material can be recirculated to treat further liquid, and the process is particularly suited to continuous operation.
